Pin Description for OE_INV = 0
PIN #
PIN NAME
PIN TYPE
DESCRIPTION
1VDDR
PWR
3.3V power for differential input clock (receiver). This VDD should be treated as an
analog power rail and filtered appropriately.
2
SRC_IN
IN
0.7 V Differential SRC TRUE input
3
SRC_IN#
IN
0.7 V Differential SRC COMPLEMENTARY input
4
GND
PWR
Ground pin.
5
VDD
PWR
Power supply, nominal 3.3V
6
DIF_1
OUT
0.7V differential true clock output
7
DIF_1#
OUT
0.7V differential Complementary clock output
8OE_1
IN
Active high input for enabling output 1.
0 =disable outputs, 1= enable outputs
9
DIF_2
OUT
0.7V differential true clock output
10
DIF_2#
OUT
0.7V differential Complementary clock output
11
VDD
PWR
Power supply, nominal 3.3V
12
BYPASS#_133_100
IN
Input to select Bypass(fan-out), QPI PLL (133MHz) or PCIe PLL (100MHz) mode
0 = Bypass mode, M= QPI, 1= PCIe PLL mode
13
SCLK
IN
Clock pin of SMBus circuitry, 5V tolerant.
14
SDATA
I/O
Data pin for SMBus circuitry, 5V tolerant.
15
PD#
IN
Asynchronous active low input pin used to power down the device. The internal
clocks are disabled and the VCO and the crystal osc. (if any) are stopped.
16
DIF_STOP#
IN
Active low input to stop differential output clocks.
17
HIGH_BW#
IN
3.3V input for selecting PLL Band Width
0 = High, 1= Low
18
VDD
PWR
Power supply, nominal 3.3V
19
DIF_5#
OUT
0.7V differential Complementary clock output
20
DIF_5
OUT
0.7V differential true clock output
21
OE_6
IN
Active high input for enabling output 6.
0 =disable outputs, 1= enable outputs
22
DIF_6#
OUT
0.7V differential Complementary clock output
23
DIF_6
OUT
0.7V differential true clock output
24
VDD
PWR
Power supply, nominal 3.3V
25
OE_INV
IN
This latched input selects the polarity of the OE pins.
0 = OE pins active high, 1 = OE pins active low (OE#)
26
IREF
OUT
This pin establishes the reference for the differential current-mode output pairs. It
requires a fixed precision resistor to ground. 475ohm is the standard value for
100ohm differential impedance. Other impedances require different values. See data
sheet.
27
GNDA
PWR
Ground pin for the PLL core.
28
VDDA
PWR
3.3V power for the PLL core.
